The discovery, in 2013, of the velocity differential spectral shift mechanism is revolutionizing astrophysics/cosmology. For instance, it provides for a superior understanding of the cosmic redshift. Moreover, it has recently been used to disprove the Sachs-Wolfe effect. In the present article, the new light-shifting concept is applied to resolving the mystery of the driving force behind astrophysical jets. It is shown how a stellar type object known as the Superneutron Star (i) converts mass to trapped radiant energy, (ii) amplifies this energy, and (iii) leaks the energy to the outside world. The main purpose is to show how photons and neutrinos can gain energy, through a wavelength contraction process. Detailed is a mechanism, based on the velocity differential in the convergent flow of nonmaterial aether, for the production of gamma particles and PeV neutrinos.
